He subsequently sat down on the couch and progressively lost consciousness. She states that he had a headache the previous week that was also sudden but not as intense. He had gone to visit his primary care physician who sent him to have a CT scan of the brain, which was normal.

He describes the headache as bounding and con- stant. You notice that his face is very ruddy in appearance. He is afebrile but looks rather lethargic and somewhat short of breath. He is afebrile and saturating 100% on pulse oximetry. One of your coworkers informs you that the patient’s wife is in another part of the emergency room with a similar presentation.
